There was one report of detection of C caviae in a person with serous ocular discharge who worked with ~200 diseased guinea pigs. The infection always involves the eye, occasionally causing signs of rhinitis, with sneezing and nasal discharge. Many different strains of chlamydia-type bacteria exist, most being highly species specific (each strain usually only infecting one or a small number of different animals/species). Diagnosis is best confirmed using PCR for chlamydial DNA on conjunctival swabs. Routine hygiene practices, such as hand washing before and after handling sick pets, may reduce the potential for transmission of these organisms from affected animals to people. Chlamydia is a sexually transmitted infection/disease that affects both men and women. Chlamydial infection is one of the most common causes of conjunctivitis in guinea pig populations, in which it is also known as guinea pig inclusion conjunctivitis (see Rodents:Bacterial Infections).

Crowded barn conditions can lead to an outbreak of pink eye. Azithromycin does not appear to be effective.

Then, clean the sheep or goat’s face. Several members of the family Chlamydiaceae have been associated with conjunctivitis in the host species they infect, including Chlamydia caviae (guinea pigs), C suis (pigs), C psittaci (birds), and C pecorum (cattle and sheep). The Chlamydia organism is the same organism that can cause enzootic abortions in ewes and does. Cell culture for Chlamydia is sensitive and specific but not widely available or practical for routine diagnostic purposes. On rare occasions, C felis and C caviae have been isolated from people living with infected cats and guinea pigs. Cattle can also suffer a pink eye infection. During show season, pink eye in sheep can be a common livestock issue. Chlamydia and Mycoplasma spp require special media; the diagnostic laboratory should be consulted before sample collection.

Chlamydia-like organisms (Parachlamydia acanthamoebae) that reside and proliferate within free-living amoeba have been detected in the eyes of cats, guinea pigs, pigs, and sheep with conjunctivitis. All Chlamydia isolates are susceptible to tetracyclines. Feline chlamydial vaccines do not provide complete protection from infection but may reduce disease severity and infection rates. The cytoplasmatic inclusion bodies, which, in 1931, Coles discovered in the corneal cells of sheep suffering from contagious keratoconjunctivitis are now considered to be the reticulate bodies of a chlamydia, Colesiota conjunctivae (synonym: Chlamydia psittaci ovis).
